Insurance adjuster question about water leak in the house?

Have a hot water leak inside the walls between two bathrooms. No water has shown up inside the house yet but its obvious with the noise its making that its there where the pipes come through the slab either rite above or below it . What is covered under homeowners policy so I have some knowledge when I speaks to Ins Co tomorrow. * when I speak to Allstate tomorrow the water meter confirms there is a leak
